AnswerAlec,
The foam door assembly would have the stainless skin but would not have all the dispenser parts and other components would have to be transferred to the new assembly. You should only need the foam door assembly which will have the wiring and tube.

AnswerHello Michael,
If you are referring to the plastic part that screws to the door, this would be the door stopper MJB63029901. If you are referring to the plastic bushing that pushes up into the metal, it is the hinge bushing J326-00012A.
